In this file, we presented the results from analyses of exposures
against computed epigenetic age accelerations (EAA) calculated using DNA
methylation data by different methods. For each exposure, we conducted
both primary analyses (likelihood ratio tests and generalized estimating
equations (GEE), adjusted for confounders) and sensitivity analyses
(likelihood ratio tests and/or generalized estimating equations (GEE)
limited to certain fuel users, not adjusted for confounders). In
addition to what’s included in the analysis plan, we also analyzed
ambient and urinary exposures.

3.1. Clusters based on model-based exposure estimates at or shortly
before the visit (clusCUR6)
The file “LEX_clusCUR6.csv” has information on current pollutant
exposures, obtained for the 2 years preceding the visit. To reduce
multi-collinearity between exposures, exposure prototypes were derived
based on hierarchical cluster analysis in combination followed by
principal components analysis. These estimates are available for 6
different prototypes (cluster variables) for a total of 161 subjects and
211 visits. The prototypes are labelled as:
CUR6_BC_PAH6 – Black carbon (BC) and 6 PAHs
CUR6_PAH31 – a large cluster of 31 PAHs
CUR6_NkF – NkF only
CUR6_PM_RET – Particulate matter (PM) and retene
CUR6_NO2 – NO2 only
CUR6_SO2 – SO2 only

Primary analysis
GEE (with confounders)
In this section, we perform the generalized estimating equations
(GEE) to evaluate the associations between each cluster within current
pollutant exposures and each Epigenetic Age Acceleration with the
formula: \[
\begin{aligned}
Y = & \beta_0 + \beta_1 * X \\
& + \beta_2 * county + \beta_3 * BMI + \beta_4 * ses + \beta_5 *
edu + \epsilon
\end{aligned}
\] where \(Y\) is one of the
epigenetic age accelerations and X is one of the cluster estimates.

GEE (with confounders, mutual adjust)
In this section, we perform the generalized estimating equations
(GEE) to evaluate the associations between each cluster within current
pollutant exposures and each Epigenetic Age Acceleration with the
formula: \[
\begin{aligned}
Y = & \beta_0 + \beta_1 * BC\_PAH6 + \beta_2 PAH31 + \beta_3 NkF
+ \beta_4 PM\_RET + \beta_5 NO2 + \beta_6 SO2 \\
& + \beta_7 * county + \beta_8 * BMI + \beta_9 * ses + \beta_10 *
edu + \epsilon
\end{aligned}
\] where \(Y\) is one of the
epigenetic age accelerations.

GEE (No confounders, mutual adjust)
In this section, we perform the generalized estimating equations
(GEE) to evaluate the associations between each cluster within current
pollutant exposures and each Epigenetic Age Acceleration with the
formula: \[
\begin{aligned}
Y = & \beta_0 + \beta_1 * BC\_PAH6 + \beta_2 PAH31 + \beta_3 NkF
+ \beta_4 PM\_RET + \beta_5 NO2 + \beta_6 SO2 \\
& + \epsilon

3.2. Clusters based on model-based exposure estimates accrued before
age 18 (clusCHLD5)
The file “LEX_clusCHLD5.csv” has information on estimated pollutant
exposures during early childhood. Estimates are available for 5
different prototypes (cluster variables) for a total of 161 subjects and
211 visits. The prototypes are labelled as:
CHLD5_X7 – a cluster of 7 air pollutants
CHLD5_X33 – a large cluster of 33 air pollutants
CHLD5_NkF – NkF only
CHLD5_NO2 – NO2 only
CHLD5_SO2 – SO2 only

Primary analysis
GEE (with confounders)
In this section, we perform the generalized estimating equations
(GEE) to evaluate the associations between each cluster within current
pollutant exposures and each Epigenetic Age Acceleration with the
formula: \[
\begin{aligned}
Y = & \beta_0 + \beta_1 * X \\
& + \beta_2 * county + \beta_3 * BMI + \beta_4 * ses + \beta_5 *
edu + \epsilon
\end{aligned}
\] where \(Y\) is one of the
epigenetic age accelerations and X is one of the cluster estimates.

Sensitivity analyses
GEE (No confounders)
In this section, we perform the generalized estimating equations
(GEE) to evaluate the associations between each cluster within current
pollutant exposures and each Epigenetic Age Acceleration with the
formula: \[
\begin{aligned}
Y = & \beta_0 + \beta_1 * X \\
& + \epsilon
\end{aligned}
\] where \(Y\) is one of the
epigenetic age accelerations and X is one of the cluster estimates.

3.3. Clusters based on model-based lifetime exposure estimates
(clusCUM6)
The file “LEX_clus CUM6.csv” has information on estimated cumulative
pollutant exposures during the lifecourse. Estimates are available for 6
different prototypes (cluster variables) for a total of 161 subjects and
211 visits. The prototypes are labelled as:
CUM6_BC_NO2_PM – a cluster of BC, NO2, and PM
CUM6_PAH36 – a large cluster of 36 PAHs
CUM6_DlP – DlP only
CUM6_NkF – NkF only
CUM6_RET – retene only
CUM6_SO2 – SO2 only

Primary analysis
GEE (with confounders)
In this section, we perform the generalized estimating equations
(GEE) to evaluate the associations between each cluster within current
pollutant exposures and each Epigenetic Age Acceleration with the
formula: \[
\begin{aligned}
Y = & \beta_0 + \beta_1 * X \\
& + \beta_2 * county + \beta_3 * BMI + \beta_4 * ses + \beta_5 *
edu + \epsilon
\end{aligned}
\] where \(Y\) is one of the
epigenetic age accelerations and X is one of the cluster estimates.

Sensitivity analyses
GEE (No confounders)
In this section, we perform the generalized estimating equations
(GEE) to evaluate the associations between each cluster within current
pollutant exposures and each Epigenetic Age Acceleration with the
formula: \[
\begin{aligned}
Y = & \beta_0 + \beta_1 * X + \epsilon
\end{aligned}
\] where \(Y\) is one of the
epigenetic age accelerations and X is one of the cluster estimates.

3.4. Clusters based on pollutant measurements (clusMEAS6)
The file “LEX_clusMEAS6.csv” has information on measured pollutant
exposures during each visit. Estimates are available for 6 different
prototypes (cluster variables) for a total of 54 subjects and 54 visits.
The prototypes are labelled as:
MEAS6_BC_ PM_RET – a cluster of BC, PM, and retene
MEAS6_X31 – a large cluster of 31 air pollutants
MEAS6_X5 – a smaller cluster of 5 air pollutants
MEAS6_DlP – DlP only
MEAS6_NkF – NkF only
MEAS6_ NO2_SO2 – NO2, and SO2

Primary analysis
GEE (with confounders)
In this section, we perform the generalized estimating equations
(GEE) to evaluate the associations between each cluster within current
pollutant exposures and each Epigenetic Age Acceleration with the
formula: \[
\begin{aligned}
Y = & \beta_0 + \beta_1 * X \\
& + \beta_2 * county + \beta_3 * BMI + \beta_4 * ses + \beta_5 *
edu + \epsilon
\end{aligned}
\] where \(Y\) is one of the
epigenetic age accelerations and X is one of the cluster estimates.

Sensitivity analyses
GEE (no confounders)
In this section, we perform the generalized estimating equations
(GEE) to evaluate the associations between each cluster within current
pollutant exposures and each Epigenetic Age Acceleration with the
formula: \[
\begin{aligned}
Y = & \beta_0 + \beta_1 * X + \epsilon
\end{aligned}
\] where \(Y\) is one of the
epigenetic age accelerations and X is one of the cluster estimates.

Primary analysis
GEE (with confounders)
In this section, we perform the generalized estimating equations
(GEE) to evaluate the associations between each cluster within current
pollutant exposures and each Epigenetic Age Acceleration with the
formula: \[
\begin{aligned}
Y = & \beta_0 + \beta_1 * X \\
& + \beta_2 * county + \beta_3 * BMI + \beta_4 * ses + \beta_5 *
edu + \epsilon
\end{aligned}
\] where \(Y\) is one of the
epigenetic age accelerations and X is one of the cluster estimates.

GEE (No confounders, mutual adjust)
In this section, we perform the generalized estimating equations
(GEE) to evaluate the associations between each cluster within current
pollutant exposures and each Epigenetic Age Acceleration with the
formula: \[
\begin{aligned}

Primary analysis
GEE (with confounders)
In the following section, we performed generalized estimating
equations (GEE) with equation \[
\begin{aligned}
Y = & \beta_0 + \beta_1 *cum\_5mc\\
& + \beta_2 * county + \beta_3 * BMI + \beta_4 * ses + \beta_5 *
edu + \epsilon
\end{aligned}
\] where \(Y\) is one of the
epigenetic age accelerations.
